Detailed Description

The utility model is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1, the cleaning system of the present embodiment includes a base station and a cleaning machine 4. The cleaning machine 4 is a floor cleaning machine, and the cleaning machine 4 includes a housing 41, a cavity 410 with an open bottom in the housing 41, and a brush head 42 disposed in the cavity 410, wherein the brush head 42 has a brush 421 at least partially disposed below the open bottom for brushing the floor. At least two brush heads 42 are arranged at intervals in the left-right direction with the traveling direction of the cleaning machine 4 as the front, and are each arranged to be rotatable relative to the housing 41, with the rotation axis of the brush heads 42 being arranged vertically. In this embodiment, there are four brush heads 42. In addition, a water spraying hole 411 for spraying water downward is provided in the chamber 410.

As shown in fig. 3 to 5, the base station includes a base 1 and an air outlet valve. The base 1 has a placement area 11 for the brush head 42 of the cleaning machine 4 to be placed therein, the top of the placement area 11 being open for the housing 41 of the cleaning machine to be placed therein. In a state where the cleaning machine 4 is located on the base station, the housing 41 is located in the placement area 11, and the water spray holes 411 are directed toward the placement area 11. The bottom plate of the placement area 11 has a cleaning groove 111 in which each brush head 42 is placed, and a cleaning member for cleaning the brush head 42 is disposed in the cleaning groove 111 of the placement area 11. Each brush head 42 corresponds to an air outlet valve and a cleaning element.

As shown in fig. 3 to 5, the air outlet valve is provided on the bottom plate of the placement area 11, and has a valve cavity 20 inside, and the valve cavity 20 has a nozzle 211 that ejects only air unidirectionally toward the brush head 42. In particular, the outlet valve is a flexible tube 2 arranged vertically, the flexible tube 2 comprising a constriction 21 and a straight section 22. Wherein the cross-sectional area of the constriction 21 gradually decreases from bottom to top and the top of the constriction 21 has the nozzle 211 as described above. In this embodiment, the opposite side walls of the constriction 21 are inclined walls 212 gradually inclined toward each other along the flow direction of the air flow in the constriction 21. The straight section 22 is located below the constricted section 21 and the cross-sectional area of the straight section 22 is equal throughout.

In order to achieve the installation of the flexible tube 2, the bottom plate of the placement area 11 is recessed downward at a position corresponding to the flexible tube 2 to form a cavity 112, the flexible tube 2 is restrained in the cavity 112, and the bottom wall of the cavity 112 has an air inlet 1121 communicating with the valve chamber 20. Specifically, the circumferential edge of the air inlet 1121 extends upward to form an annular wall 1122, and the lower end of the flexible tube 2 is fitted over the outer periphery of the annular wall 1122.

The cleaning member is a raised strip 3 which is arranged on the bottom plate of the placement area 11 and extends upwards, and the raised strip 3 is positioned in front of the air outlet valve. In a state where the housing 41 of the cleaning machine 4 is placed in the placement area 11, the protruding strip 3 is located on the rotational path of the brush 421 and in front of the corresponding flexible tube. The two convex strips 3 on the left side gradually incline towards the right from front to back, and the two convex strips 3 on the right side gradually incline towards the left from front to back.

The cleaning process of the brush head of the cleaning machine is as follows:

When the self-cleaning is carried out, the chamber is in a normal pressure state, and the nozzle is in a closed state under the action of self elasticity, so that water cannot leak out of the valve port; when the cavity is in a negative pressure state, the nozzle is opened under the action of the negative pressure, air is introduced into the placement area and mixed into water flow, so that the bubbles can wash the surface of the brush piece of the brush head, the effect similar to 'bubble washing' is achieved, and the cleaning capability is improved.
